First attempt at making a PC board with the GF


#1

Here’s a look at the GF resist (er, spray paint) removal results. Speed 500, full power, 600+ lpi.

Will update after ferric chloride etching! :slight_smile:


#2

Neato! :grinning:


#3

so…

so when you dunk it in the ferric cloride the copper traces go away? of does it react with the spray paint? I haven’t made a PCB before, but it is certainly on my todo list, to create our halloween decorations.


#4

Yes, the ferric chloride removes the exposed copper. You then wash off the resist to expose the copper underneath.

Thanks!

That’s what I thought, but always better to double check, and get it right. :slight_smile:


#6

Ok! After allowing the ferric chloride to warm up before etching (it was chilly in the garage where I had it stashed), etching went fairly well!

Now I’m curious about how fine I might be able to go. This is just a power distribution board, so fine traces weren’t necessary.


#7

Wow, that’s pretty cool application for the GF! I’ll have to give it a try in the not-too-distant future…

Yah. It really does not work cold.
